Hi all,

Thank you John for your quick reply to my previous email.  I've tried out both of your 
suggestions below.  It still does work.  I might have done something incorrectly as I 
am very new to these stuffs.  Here are the steps that I've taken:
1) I create a file called openMe_js with JavaScript function. Then, I add it to the 
same dir as htmlPreview.  The function looks something like:
<script language="javascript">
function openMe(URL){

BTW, I've put this code directly in htmlPreview.

2) Next, I add one of the two methods that you've suggested to the head of htmlPreview:
> <script language="JavaScript">
> <dtml-var name="openMe_js">
> </script>


> <SCRIPT LANGUAGE="JavaScript" SRC="<dtml-var 

3) Finally, I add <A href="javascript:openMe('<dtml-var url html_quote>')"><dtml-var 
linktext html_quote></A>
to one of the sections in htmlPreview. 

Sorry if the email is a bit lengthy.  I want to be sure that I'm doing it right.  
Thank you all in advance to helping me.
